VACUUM FILTER SET

► VACUUM FILTER FUNNEL CLASSIFICATION BY MATERIAL AND FILTER DIAMETER

A. Classification of Vacuum Filter Funnels by Material:

1. Glass Vacuum Filter Funnel

   • Made from glass material.
   • This material is highly resistant to heat and chemical corrosion.
   • However, it is prone to breakage if dropped and cannot withstand HF acid.

2. Plastic Vacuum Filter Funnel

   • Made from PES (Polyethersulfone), PC (Polycarbonate), or PP (Polypropylene).
   • Can be sterilized by autoclaving. It is resistant to impact and breakage.

3. Stainless Steel Vacuum Filter Funnel

   • Made from stainless steel.
   • It is resistant to heat, can be autoclaved, and is highly resistant to chemical corrosion.
   • More expensive than the PES plastic or glass funnels.
